Factual error: In the movie, Houdini's death is caused by failing to escape from a Chinese Water Torture Cell following an injury with a prop sword. In reality, Houdini died of a burst appendix after being punched in the stomach.

Continuity mistake: Just after Houdini returns to the United States from his European tour, he stages a publicity stunt. The lady in the apartment opens her window shade and sees Houdini hanging upside down, directly outside the window. When it cuts to an outside shot, he is now suspended above the roof line, where the woman would not be able to see him.
